Sure keep the chassis balanced but most non-proficient drivers will release brake pressure during the blip. Why stack the chips against you? Brake bad habits (err I mean break) as soon as you recognize them so driving faster is simpler/easier.

Well in that case, Id tell them to focus more on the driving at hand then banging out the prefect downshift. There are many very fast driver I know that don't heel/toe. Just saying...
